Meeting rail engaging member for storm windows



Sepia 9 1950 STORM WINDOWS v ma, v M WM I l WW1 if INVENTOR. CV/ffora/Z.14/ 6 Patented Sept. 1950 This invention relates to storm}windowsinldeparting-from the spirit offthe invengeneral and in particular to meansfor locking the meeting rails of a double hung storm window as; semblyto one another.

The principal object of the invention is the provision of a device forholding the meeting rails of a double hung storm window assembly inengagement with one another.

A further object, of the invention: the it -f vision of a deviceengageable in one of the'meet ing rails of thedouble hungistorm windowassembly for joining the meeting rails of the said window assembly whenin closed position. v I A stillfurther object of the invention is theprovision of an extruded metal-part engageable in a metallic sash for.self retention therein and having means thereon for engaging anadjacent; metallic sash and urging. the-same toward the first mentionedsash. i

The meeting rail engaging member forstorjm windows shown and describedherein comprises a;

simple and efficient meansfor securing metallic framed storm window sashto one another and particularly the meeting rails'thereof which haveheretofore presented a problem in storm window construction. a 1

As is known in the art, relatively lightweight .metal extrusions arecommonly employed as glass :frames to form storm window sash and such:storm window sash are commonly'positioned vin :a mounting frame indouble hung relation for vertical sliding motion therein. -The sides'a'nd top and bottom portions of the'sash which enigage the frame arethus secured in an air-tight manner. 1 ,1:

. The meeting rails of the sash are normally positioned adjacent oneanother and heretofore have not been secured to one another with theresult that wind pressure or deflection of the sash themselves separatedthe meeting rails and destroyed the effectiveness of the storm windowassembly. The present invention eliminates this difficulty as it causesthe meeting rails to move into close engagement with one another andprovides tension therebetween thus enabling each of the meeting rails tosupport the other and at the same time maintain themselves in desirableface to face engagement.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed tion..

{The invention isillustrated in the accompanying drawing, whereinn 5Figure 1 is a vertical section of a portion of the tmeeting rails of apair of double hung storm window sash.

Figure 2 is a vertical section of a portion of the meeting rails of apair of double hung storm '10 windowsash in open position. I

(iii v.liiigure is plan view of a portion of the meeting rails 9f apairof' d ouble hung storm window a h lig nre 4 is a perspective elevationof the meetmg rail engaging member.

2 in particular it will'be seen that portions of a pair; of double hungstorm windowsash have been disclosed the transparent pane of the upper outer.;;sash beinggindicatedby thenumeral II] m and its meeting railmetallic frame on. its" lower edge;being indicated by the numeral III.The transparent pane of the inner lower sash is indicated by thenurneralI2 and the metallic meeting rail thereof ,is indicated by the numeralI3.

The transparentpanes II] and I2 are secured at themeeting rails II andI3 b y;metallic splines I4 and, I5, respectively, asis customary instorm window practice. In Figure 1", Qfthe drawings the meeting rails.II. and l3,-.;respectively, are shownin faceto face engagement which istheir normal position when thestormwindow'is closed. In Figure,.2 of thedrawings the meeting rails II and ISar'e shown in disengaged relation asis the case Whenthelower inner pane i2 is elevated or the upperouterpane Ill lowered.

Still referring to Figures 1. and 2 of the drawings it will be observedthat the upper edge of the meeting rail I3, which is positioned on theupper edge of the pane. I2 of the lower inner sash, has a relativelyshort section of an engaging member Ifi slidably engaged therein andpreferably positioned in the center thereof with respect to the sidesthereof (not shown). The engaging member I6 comprises an extruded metalshape, the body portion of which registers within a channel I! of themeeting rail I3 and par-' tially beneath a flange I8 thereof. The bodyportion of the engaging member I6 is formed to overlie the upper edgesof the meeting rail I3 by reason of a pair of flanges I9 and 20, theflange I9 being relatively short and the flange 20 extending outwardlyand having its outermost, lowermost edge slightly outturned as indicatedby the numeral 2|.

The engaging member I6 is shown in perspec- By referring to the drawingsand Figures land 3 tive in Figure 4 but it will be observed by referringthereto that its cross sectional shape is such that it will registerwith the channel I! of the meeting rail l3 and thereby enable the sameto be slid into position longitudinally thereof atfthe-timeof formationof the storm sash, and'to be self retaining therein. In position, asshown in Figures 1, 2 and 3 of the drawings, the engaging member I6 liesmidway between the sides of the sash so that the depending flange 20will slidably engage and tension a spline receiving channel 22 formed inthe upper edge of the meeting rail II which is on the lower edge of thetransparent pane [0. The action of the engaging member is illustrated inFigures 1 and 2' of the drawings.

In Figure 2 of the drawings the sash are shown her and the channeledpart interfitting with each other to form an interlocking connectionbetween said member and said channeled part, the body part of saidmember having a laterally extending portion overlying the upper edge ofthe straight inner side wall portion of the last mentioned channeledpart, and a flange extending downwardly from said laterally extendingportion to fit against the inner side of the straight inner sid wallportion of the channeled part of the meeting rail of the upper sash.

2. A double hung storm window assembly comprising upper and lowervertically slidable sashes in disengaged or partly open position withthe meeting rails out of engagement. In Figure 1 of the drawings thesash ar shown in engaged or fully closed position, it being observedthat the meeting rails H and 13 are in face to face engagement and heldin that engagement by the tensioning action of the engaging member 16and specifically the depending flange 20 thereof which engages themeeting rail ll.

Itwill thus be seen that a simple and efficient device has beendisclosed which may be inex pensively formed and easily applied to stormwindow constructions and particularly those 'employing metallic framessuch as shown herein. It Will also be seen that in operation theengaging member will efiicie'ntly hold the meeting rails of the stormwindow sash in tight face to-face engagenient whereby they becomeself-supporting and whereby any possibility of air leakage at this pointof the storm window construction is eliminated.-

Having thus described my invention, what I claim is:

1. A double hung storm window comprising upper and lower verticallyslidable sashes each including a metal frame, the meeting rails of the;

close fitting engagement with the straight side wall portions of saidchanneled part, said memeach including a metal frame, the meeting railsof the frames of the sashes each comprising an upwardly facing channeledpart, and the channeled parts of the meeting rails having straight innerside Wall portions to fit one against the other when the sashes are inclosed position, the straight inner side wall portion of the channeled Ipart of the meeting rail of the lower sash having at its upper edge aflange extending laterally to the inner side thereof, and a member forholding the meeting rails of the sashes in engagement with each otherwhen the same are in closed position, said member comprising a mainlongitudinally ext-endingbody parthaving at one side .at its upper parta longitudinally extending shouldered portion, said body part fittinginto the channeled part ofthe meeting rail of the lower sash withitsshouldered portion in interlocking engagement with the laterallyextending flange on said side wall portion, and said body a part havinga laterally extending portion overlying the upper edge of said straightside wall portion, and a flange extending downwardly from said laterallyextending portion to fit against the inner side of the straight innerside wall portion of the channeled part of the meeting, rail of theupper sash.
